Things seem to be going well for Jana Kramer and Brantley Gilbert, as is evident by a rumored recent purchase -- and it's a big one.

The fellow country singers' romance has been heating up this winter, and apparently that's been topped by Kramer and Gilbert buying a house together, according to Nashville Gab. The report originally popped up at OMG, a Yahoo gossip site that insists that the country couple is getting very serious.

"I am really happy,” Kramer says when speaking of her love life. “[Brantley] is so wonderful, I cannot stop smiling around him. He surprises me with gifts ‘just because.’”

One of the sweet things Gilbert has done lately is nurse Kramer back to health after she was plagued with exhaustion and dehydration while touring with Brad Paisley. At a show in West Palm Springs, Fla., Gilbert noticed that Kramer didn't look quite right during one of her sets. He left his seat and went backstage to make sure she was okay. She wasn't -- she spent some of her 29th birthday at home in bed following a hospital visit.

The serious state of the couple's dating relationship comes as a bit of a surprise to fans. At the CMA Awards in early November, Kramer walked the red carpet solo, and she was pretty tight-lipped about her man. Now, the relationship is hot, hot, hot!
